// npm i x402-fetch viem
import { wrapFetchWithPayment } from "x402-fetch";
import { createWalletClient, http } from "viem";
import { privateKeyToAccount } from "viem/accounts";
import { base } from "viem/chains";

const account = privateKeyToAccount(process.env.PRIVATE_KEY); // funds USDC on Base
const wallet = createWalletClient({ account, chain: base, transport: http() });
const fetchWithPay = wrapFetchWithPayment(fetch, wallet);

// Pays the $0.005 USDC automatically on the 402, then returns the real response:
const res = await fetchWithPay("https://qr.x402tools.xyz/v1/generate/styled", { method: "POST" });
console.log(await res.json());

# pip install x402 eth-account httpx
import os, asyncio
from eth_account import Account
from x402.clients.httpx import x402HttpxClient

account = Account.from_key(os.environ["PRIVATE_KEY"])  # funds USDC on Base

async def main():
    async with x402HttpxClient(account=account) as client:
        # x402 handles the 402 -> pay ($0.005 USDC) -> retry automatically
        r = await client.get("https://qr.x402tools.xyz/v1/generate/styled")
        print((await r.aread()).decode())

# 1) An unpaid request returns HTTP 402 with the exact payment terms:
curl -i -X POST "https://qr.x402tools.xyz/v1/generate/styled" \
  -H 'content-type: application/json' \
  -d '{"backgroundColor": "#1e1b4b", "dotType": "rounded", "gradient": {"from": "#6366f1", "to": "#ec4899"}, "size": 512, "text": "https://example.com"}'

# 2) Paying + retrying requires an x402 client that can sign the USDC
#    authorization (curl alone cannot). See the JS / Python tabs below.
